Development of the Frontal and Temporal Regions during the Last 3 Months (video) King's College London Share Print E-Mail Loading video... Caption This video shows the development of the frontal and temporal regions of the cerebral cortex in preterm infants during the last three months before the normal time of birth, turning from red to blue as it matures. The primary motor and sensory regions are well developed at the beginning of the sequence, while much of the association cortex involved in complex functions develop rapidly over this period, particularly in the most frontal regions. Despite this rapid maturation, premature babies are less developed at term than infants born at the normal time.
